On September 21, all the AQI indicators recorded from the monitoring stations of Shalu, Xitun, Dali and Wenshan all showed that fine suspended particles (PM2.5) reached very poor grades. The Environmental Protection Bureau (EPB) of Taichung City Government has immediately issued a warning to the general public and activated the emergency response measures to rectify the poor air quality situation.

The EPB has been using the continuous emission monitoring systems (CEMS) to collect data from the major pollution sources and enhancing street sweeping and washing to suppress dust in such administrative districts as Dajia, Dali, Wuqi, Shalu, Fengyuan, and Wufeng. Moreover, the EPB has been strengthening inspection on construction sites, the factories emitting suspended particles, and the sand and gravel plants. Any open burning has also been prohibited.

Construction sites are required to implement air pollution control measures, spray water more frequently on the paths and the bare ground within the construction sites, and cover up the aggregate heaps. Those factories emitting suspended particles are required to check their air pollution control equipment. Sand and gravel plants are asked to keep dust and particulate pollutants from flying from the bare ground (by spraying water on it and covering it with dust nets or straw mats) and clean the body and tires of vehicles before they leave the plants. In addition, inspectors are stationed at commanding heights to check if there is open burning. It is hoped to keep air quality from deteriorating further.

The EPB has also issued a warning that air quality has been worsening to its peak, and people suffering from respiratory diseases or asthma, the elderly, the children and the weak are advised to avoid strenuous outdoor activities and wear masks when going out during this period of time. People are also urged to take public transportation to help reduce air pollutant emissions from vehicles.
